The evening of February 18, 2015
brings a special celestial event: A combined New Moon, Black Moon, and
Supermoon. It’s always fun to spend time looking at the evening sky.
Here's some information from Stephen Luntz's article "Black Supermoon Will Be Visible Wednesday Night.
"Black moons, like blue moons, are not actually colored any differently
than others...The name refers either to the second new moon in a month or to the third in a season with four new moons." [using] astronomical, rather than
meteorological seasons, the northern
hemisphere's winter runs from the December solstice to the March
equinox..."
